'Room Sealed' Stove recommendations

Troy McClure

We are building airtight house, well insulated. Have made provision for 2 stoves, one has 4" external air coming in under the floor the other from throught wall. We wanted a cassette stove and a free standing stove.
I had thought a stove with external air supply would do but I am told we need 'room sealed' stoves. Anything else would be dangerous.

Allowing for the above. Can anyone recommend stoves (makes/models) that are 'ROOM SEALED' ?? A list would be great!! Good value also required as I know stove price can be nuts.

Also looking for a Knowledgeable qualified competent installer that has experience of air tight senario in the south East. Pm me if neccessary.

We have been getting alot of misinformation on this from so call experts, so please only those who genuinely know, or have direct experience of above criteria please.

Thanks for that. Westfire have 3 stoves that are room sealed I am told.

I called Westfire in Denmark today and spoke to technical guy there. He said in Denmark there are alot of airtight houses with MHRV. He said alot of the time these have stoves with 'no' external air intake in the houses and they just up the air input of the MV by 20% to cause a positive pressure to feed the stove the air it needs. He said he does this in his own home.
I have to say I never heard this before and fear to think what may happen if you go to bed with a fire lighting and the MV goes on the blink!

It seems a questionable set up what with a MHRV systems inherent variability (over time - filters clogging, for instance) and, as you say, if it malfunctions or there's a break in power supply.

Can you say what the three room-sealed models are (before the mods snip the makers name )? Still curious as to the differentiation between 'room-sealed' and external air supplied....

As I understand it...

"Room sealed" means the stove depends entirely on the external Air intake for combustion.

"Non room sealed" with the external air intake have air vents on the stove but they are closeable. There'd be no guarantee these don't draw air from the room. My personal opinion on this is that these are models that manufacturers previously had and they did the bare minimum they could do to meet a market need.

I'm open to correction however.

On the theory from Denmark, this sounds like utter nonsense to me. The point of the external air intake is to avoid using warm internal air for combustion, in effect dumping heat out of the house. When the stove isn't lit you'd be in a situation of net heat loss because warm air would be forced up the flue/chimney.

Also, the pressure could push moisture into the structure. Again, not a good thing.

This is a bloody mine field!

Can you PM me the details. Also have you looked at Stovex ? I was going choose them ..any opinions ??

They look nice but their "room sealing kit" as I read it smacks of solely fitting an air supply kit. No mention of how the stove is sealed from the room...

They are completely room sealed if you attach an outside air supply pipe, as all of the combustion air enters from an opening to the rear where you attach the pipe. I think if you look at the actual brochure and installation manual online this is very clear.

Of course some people will use the stove without attaching the pipe, in which case it is obviously not room sealed.

Many stoves that can take an outside air supply pipe remain non-room sealed even with the pipe, because some combustion air, often for the airwash at the front, continues to enter from the room. Anybody who is looking for a room sealed stove should be wise to this.

Can please add me to the PM list? Thanks

Ah, I see it now. A single air inlet....

Has anyone actually installed an external air supply for such stoves? If your a good distance away from an external wall, I suppose you have to go through the slab, but then how is this terminated externally, do you have to rise back up into the external wall.

Or can you go to the roof gable.

Or has anyone installed a Scan stove - I am considering the 58_7.

We cut a slot out of the floor insulation to take the 3-4m length of ducting from the stove to - and through - the external wall. As it happened we had decking outside of that so no problems with footpaths, etc, just terminated the ducting at the face of the decking.

Are these 100% room sealed. I can see they have external air but not sure they are room sealed.

Why am I not allowed to link to products here that I am not affiliated with in any way, but I can in plumbing & heating? Ie stoves questions and answers. Whats the difference? Many thanks.

Hi the ones beggining with C, certainly are. Can't remember the others but see advice below:)

Its very easy to spot as when you look at a picture of the stove it has no air vents at the front and so totally room sealed:).

every forum has its own rules.
as this forum is 'construction and planning' the amount of materials, products and processes that could be discussed is endless. Much more so than specific fora like plumbing.

We here have taken the view that if we allow anonymous people to publicly post their views / opinions then we are:
1. leaving the forum open to shills who say their product is best
2. leave it open for competitors to bad mouth others
3. give a forum to disgruntled customers to rant without reply
4. gives free advertising

each of the above leaves it open for boards.ie (a privately owned website) to be sued, a situation which us volunteer moderators are dead set against.

I wont comment on how another forum is run, each to their own, but if you are posting across many fora then at a minimum read each forums charter before posting.

I recently installed a stove with external air supply. As stove loacted at external wall I simply put the external air pipe directly through the wall and sealed around it. This part was fine .. the problem I had was where the external air kit attached to the body of stove. When first installed I could feel a draft blowing from the bottom of stove so got installer back and he sealed the kit to the stove again. It is much better now but I wouldn't claim its room sealed especially around the lever for adjusting the level of air coming through the kit. In my view the external air kit is a pretty crude device that's fine in a house without air tight pretensions - not so sure otherwise. However, obviously many time better than having a vent in the corner of the room. I was considering installing some kind of a damper on the actual external air pipe which could be shut down when stove not operating thereby making it truly airtight.

Does such a device exist.? Where would you get one? How would it be opened/closed?

Ok, the PHI insisted I install one of these. It's bascally a 6 inch long tube of metal with a disc that pivots on a bar inside it.

It can be bought with a motor that can be wired off a switch.

The motorized version is 450 euro. It doesn't seal fully because in germany where I sourced it, it is apparently not legal to fully close off a flue at any time. Minimal airflow keeps it dry etc.

I've a second one in the flue itself near the airtightness line in the roof.

They are a complete and total balls.

I fully understand that people are concerned but I really think this is a step too far with little or no real practical value.

Thanks for the info .. I think I will be forgetting about that little idea for a while .. €450! Whatever about the one on the freah air inlet pipe I'd be concerned about having one on the flue in case it malfunctioned.

I would love a pm for this also please. THANKS

I will forward some of the names I was given. However not all were actually room sealed, they only looked like they were.

If anyone knows a room sealed stove, 4-6kw freestanding that has air intake on the underside. please PM me.

beyondpassive

There is a Qualplex type of flexible air supply heat resistant pipe I've seen used in some installations.
Anyway Stoves's in the house are a bit old skool, heres where its at now:

Hi,

Could i also get a list of recommended room sealed stoves - looking for low room output (4-5kw), room sealed with a boiler preferably.

Many thanks,

Just remember the rated power is its max output with seasoned slow growth timber. Any fire will only burn at its top rating for 15-30 mins max then will drop significantly. Personally I found the Brunner type stoves performed well in airtests and have heard some good reports on performance. Unless you're working from home or the room is very small, I dont see the point of a back boiler. In new houses people tend to use the stove much less than originally anticipated.
